A Hahnah crab assisted Toa Mahri Jaller during the Toa Mahri's underwater mission in the Pit.1, 2, 3, 4, 5 Shortly after the Toa Mahri arrived in the Pit, this friendly creature was attracted to a lukewarm flame made by Jaller, as heat and light were a rarity so far beneath the sea.6 It befriended Jaller and from then on followed him everywhere.2 It could use its claws to tear apart sea squid, once rescuing Kongu from a sea squid attack.6 Before the Toa Mahri launched a major attack on the Barraki at the Razor Whale's Teeth to retrieve the Mask of Life, Jaller, at Hewkii's suggestion, attached his Cordak blaster to the Hahnah crab's back1, 7, 3, 4 in order to serve as a diversion.2 When the Toa attacked, a rocket launched from the crab's back startled Mantax, allowing Jaller to tackle him.8 The crab's back-mounted Cordak blaster, combined with Jaller's aquatic power blade, allowed Jaller to hit enemies from two directions at once.1, 7, 4 Jaller later took the Cordak blaster off before using it to destroy the Cord.8, 9 When Matoro teleported the Toa Mahri back to Metru Nui, Jaller's Hahnah crab was left behind in the ocean,10 where it probably remained after Aqua Magna reunited with Spherus Magna.11
